It's not only that we're suited to think mathematically; other animals--some that we wouldn't label complex--are also capable of thinking mathematically (i.e. ants and vectors). It's not only that we think in this manner, but it's so inherent in our makeup, that we do it somewhat unconsciously. When you add that non-human animals think this way, the conclusion seems inescapable.
